After satellite images failed to lead rescuers to the missing chopper of Arunachal Pradesh chief minister Dorjee Khandu four days after he went missing, the search mission shifted focus to Bhutan.

"Torrential rains and steep inclines slowed down the pace of the well-trained rescuers who began trekking early morning, but they got nothing when they reached the two spots well past noon," said Union minister V Narayanasamy in state capital Itanagar.

The rescuers are expected to re-scan the areas at 13,000-14,000 ft and would be joined by more forces by Wednesday.

The 'disappointment' made other search parties shift focus to five other spots - four in West Kameng district of Arunachal Pradesh, and the fifth in the Paktujiji area in the adjoining Trashi Yangtse district of Bhutan.

When asked if New Delhi would seek China's help to locate the chopper, Narayanasamy said, "The issue of taking Chinese help did crop up. But the Crisis Management Committee (formed with members drawn from Arunachal Pradesh) ruled it out."

The Union minister also ruled out the appointment of a caretaker CM for the time being.
